Beat-up, stale organisation (7)

I believe the answer is:

pulsate

'beat' is the definition.
(I know that beat can be written as pulsate)

'up stale organisation' is the wordplay.
'organisation' is an anagram indicator.
'up'+'stale'='upstale'
'upstale' is an anagram of 'PULSATE'.

(Other definitions for pulsate that I've seen before include "Produce a regular throbbing sensation" , "Throb regularly like heart" , "thrill" , "Expand and contract regularly" .)

I've seen this clue in The Daily Express.
